Any day now the cicadas will be emerging all along the east coast. The cicadas in this cycle, known as Brood II, have been maturing underground for the last seventeen years.
They will crawl up when the ground temperature reaches 64 degrees and experts expect there to be nearly nearly 600 cicadas for ever one person. They emerge to mate, but they will also make a lot of noise.
Rothenberg told Here and Now‘s Robin Young that what may sound like a drone to some is actually a very complex sound.
